Serverless computing allows developers to build and run applications without managing servers. Functions as a Service (FaaS) platforms, such as AWS Lambda or Azure Functions, automatically handle infrastructure scaling and provisioning. The primary benefits of adopting a serverless architecture are massive cost savings—you only pay for compute time when your code is running—and inherently superior scalability. When traffic spikes, the provider automatically executes more instances of your function. However, developers must be mindful of vendor lock-in and the cold start problem, where functions take a moment to wake up after periods of inactivity.
